3003 Aluminum Foil Supplier

3003 aluminum foil overview

Aluminum foil 3003 is the most widely used alloy in the 3000 series. 3003 alloy aluminum foil adds metallic manganese to improve the physical properties of the aluminum foil. It is also known as the “Al-Mn” series metal and has a series of remarkable properties and a wide range of applications.

3003 aluminum alloy foil material properties

3003 aluminum foil is mainly composed of aluminum, manganese and other elements. The addition of manganese element significantly improves its strength and corrosion resistance. 3003 aluminum foil is about 10% stronger than 1100, but the overall strength is not high (slightly higher than 1000 series industrial pure aluminum). At the same time, it has excellent anti-rust properties. Its corrosion resistance is very good, close to the corrosion resistance of industrial pure aluminum. It has good corrosion resistance to the atmosphere, fresh water, sea water, food, organic acids, gasoline, neutral inorganic salt water solutions, etc. The corrosion resistance in dilute acid is also very good.
